The most common estimated parameters in DCE-MRI are Ktrans and Ve. The process of Ktrans estimation is not easy. but the IAUC is more feasible. In this study, we aim to further investigate the application of mIAUCktrans in clinical and find the correlation between mIAUCktrans and Ktrans. With the correlation coefficients of 0.95, mIAUCktrans was more correlated with Ktrans. Since the high correlation between Ktrans and mIAUCktrans was demonstrated in this study, it reveals that mIAUCktrans could be an alternative for physiological condition evaluation in DCE-MRI.
